The equation 9+12m=6+15(m-1) models the following situation: Movie-rental company A charges a sign-up fee of $9 plus $12 per month, and company B charges $6 for the first month plus $15 per month after that. At a certain number of months, the cost of the two companies is equal. Which equation is a simplified version of the one above? 3m = 15 9 + 15m = 12m – 1 3m = 18 9 + 6 – 15 = 15m – 12m
Answers
Answer:
3m = 18

Answers
The square root of the decimal number is √0.0016 = 0.04
How to find the square root of the decimal number?Here we can find the square root of the decimal number:
N = 0.0016
Notice that we can write this number as:
0.0016 = 16*10⁻⁴
Now we can take the square root of that, so we will get:
√(16*10⁻⁴)
We can distribute the square root to get:
√16*√10⁻⁴
These two are easy, we will get:
√16*√10⁻⁴ = 4*10⁻² = 0.04

Step-by-step explanation:
x + 130° = 180° { being linear pair }
x = 180° - 130°
x = 50°
And we can see in the triangle two sides are equal so it is an isosceles triangle so the base angles are also equal.
Then
y + 50° + 50° = 180° { being sum of angles of triangle }
y + 100° = 180°
y = 180° - 100°
y = 80°

Answers
Answer:
76%
Explanation:
We want to write a percentage that is between 3/4 and 7/9.
First, begin by converting each of the fractions to its decimal equivalent.
\(\begin{gathered} \frac{3}{4}=0.75 \\ \frac{7}{9}\approx0.78 \end{gathered}\)Thus, we can say that:
\(\begin{gathered} 0.75<0.76<0.78 \\ 0.76=0.76\times100=76\% \end{gathered}\)A percentage that is in between 3/4 and 7/9 is 76%.

Answers
The gravitational potential energy of the vacationers will decrease as they approach the end of the pier.
How we get the gravitational potential energy?As the vacationers approach the end of the pier, their gravitational potential energy will decrease.
Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It depends on the height of the object and the acceleration due to gravity.
In this scenario, as the vacationers walk out on the horizontal pier, their height above the ground remains constant. Since the height does not change, the gravitational potential energy also remains constant.
However, as they approach the end of the pier, their distance from the center of the Earth decreases. As a result, the gravitational potential energy decreases because it is directly proportional to the distance from the center of the Earth.

A sphere is inscribed in a cube with edge length 9 inches. Then a smaller cube is inscribed in the sphere. How many cubic inches are in the volume of the inscribed cube
Answers
To find the volume of the inscribed cube, we need to determine the edge length of the cube first. Let's denote the edge length of the inscribed cube as "x".
In a cube inscribed in a sphere, the diameter of the sphere is equal to the diagonal of the cube. Therefore, the diameter of the sphere is equal to the space diagonal of the large cube, which is given as 9 inches.
The space diagonal of a cube with edge length "a" can be found using the Pythagorean theorem:
Diagonal² = a² + a² + a²
Diagonal² = 3a²
Since the diameter of the sphere is 9 inches, we can write:
3a² = 9²
3a² = 81
a² = 81 / 3
a² = 27
a = √27
a = 3√3
Now we know the edge length of the large cube, which is 3√3 inches. The volume of a cube is given by V = a³, where "a" is the edge length.
Volume of the inscribed cube:
V = (3√3)³
V = 3³ * (√3)³
V = 27 * 3
V = 81 cubic inches
Therefore, the volume of the inscribed cube is 81 cubic inches.
The volume of the cube inscribed in the sphere, given the sphere is inscribed in a cube with an edge length of 9 inches, is 81 cubic inches.

In pentagon $MATHS$, $\angle M \cong \angle T \cong \angle H$ and $\angle A$ is supplementary to $\angle S$. How many degrees are in the measure of $\angle H$?
Answers
Answer:
H = 120°
Step-by-step explanation:
The sum of the internal angles of a polygon with n sides is given by the formula:
S = (n-2)*180
So, for a pentagon, we have n = 5, then:
S = (5-2)*180 = 540°
So we have that:
M + A + T + H + S = 540° (eq1)
M = T = H (eq2)
A + S = 180° (eq3)
Using the second and third equation in the first one, we have:
H + H + H + 180 = 540
3H = 360
H = 120°

Answers
(a) The variable educ might be endogenous
(b) The variable brthord is birth order (one for the first-born child, two for a second-born child and so on) could be used as an instrument for educ in equation
